Manchester United eased past a Swansea side that was tacked down by a sense of laxity for the greater part of the game thanks to goals from Romelu Lukaku and Alexis Sanchez. Going into the game just having let go of the second spot on the Premier League table to Liverpool, Jose Mourinho would have wanted nothing else but all three points from his side.With an authoritative first half performance where they seemed to absolutely relish the freedom of Old Trafford, afforded to them by the traveling Swans, United's attackers ran riot as Carlos Carvalhal's side consistently came up second best everywhere.It was a typical Red Devils performance in so much as they have ended the game perhaps 2 or 3 goals short of what they should have got, owing to some impressive all-around play except for in front of goal.Meanwhile, the relegation battle has got all the more riveting as the Swans get further absorbed into the thick of things. Without hanging fire, let's get to the key talking points from the game.#5 United play some of their best football in the first half with an authentic all-round displayBringing the swagger back to Old TraffordWithin the first five minutes, there was a feeling that some of the swagger had returned and was waiting by the gates at Old Trafford. Then the Red Army bombed forward with some intricate passing and clever movement to throw Swansea off balance.Mourinho deployed Paul Pogba in a deeper role alongside Nemanja Matic but thanks to the room afforded to him, Pogba decided to frolic about and, with him dragging the game by its ears, there was only one way the game was going.Matic put in yet another fine shift as he thwarted anything that the Swans created through the middle with some timely interceptions and reading of the game.Going forward, the United players, agile and mobile even in the absence of Anthony Martial and Marcus Rashford, offered the Swans no peace of mind. Jesse Lingard, in particular, was a thorn in the flesh for Carvalhal's men with his turns and ability to weave in some defence-splitting passes.They should have added more for all the creativity they brought to the ground but it was not to be. But add some stoic defending to the mix and as soon as United scored those 2 goals, the game was done and dusted.
